To all 'whom t may c'udnaem:

Be it,known that-L'JOHN MCTAMMANY, a citizenof'the United States', and aresident 'of Stamford,' inthe cohnty of Faireld and State ofConnecticut, have invented certain new and usefullmprovements inAutomatic Type-Writer Operators, of which the follow# ing is aspecification.

' typewriter 1n a predetermined order' 'deter-l This invention relatesto -an automatc ma chine controlled by a perforated mastersheetfor'depressing the keys ofthe ordinary mined by perforations made in amastersheet, the said sheetv being combined with mechanism whichsupplies power'tovthe typewriter keys in suchmanner'as to depress thesame one by one. The invention has for its object', first, to provide asimple sheet-controlled operating mechaism'in which the power employedistransmitt'ed directly and positively tothe typewriter Skeys'withoutthe employment of pneumatic or other like actuating means controlled bythe sheet.

The invention also has for its object to provide an improvedmaster-sheet, the key operatingperforations of which are designated vsothat the letter or. character which operation; Fig. 5 represents a rear`elevation of the machine; Fig. 6 represents a sectlon 6-6 of `Fig-5;Fig. 7 represents a l a portion of the master-sheet.

on 1i i vviewldef 'T he same reference characters indicate the sameparts in all the gures.

In .the drawings,-12, 12 represent the supporting portions vof the frameof an crdinary typewriter, and l13 represents one of thekeys or keylevers, these belng parts of the' ordinary printing mechanism of the tnewr-fter which forms no art of m'y in-. y` p with t e spacenhetween-twoof the teethfQ f relie The mechanism embodving' myvintention.,

is mounted in a'ca'sing which constitutes a oase adapted to support thetypewriter, saidcaslng, as here shown, comprising an lupper. section 14.to which the parts 12 of the type writer frame are detachably secured by60' screws'v15, anda .lower'or' ,base section 16 supportlngthese'ction14 and hinged thereto at 17 so that said section 14, and thetypewriter attached thereto, may be swungupfwardly to ,expose .the`mechanism of the operator. 1,8 represents a shaft: mounted at its endsin -two opposite side-pieces of the casing section 1 4 andextendinghorizontally across the 1nterior. of said section. Upon the shaft 70 18are mounted hubs 19 corresponding in number to the printing charactersand key levers -of the typewriter and adapted to be independentlyrotated by friction as hereinafter described. To each hub 19 is attached75,

a star lwheel 20, the teethl of which hre preferably 'formed as shown bvFigs. 1, 3 and 4.

21-,represent's a feed roll which is formed es .an elongatedv spur gear,said'ro'lllhaving L longitudmal vgear teeth 22 separated by'in- 80terdental spacesof uniform width, the teethv being alsof uniform width.

` 23 represents a master-sheet of paperor fother suitablefieXible'ma-terial"having keyfoperating perforations 24.' The sheet23;'85

passes between the feed rolli2l Vand the series of star wheels 20 .andis supported and driven by thefeed roll, the latter being provided atits central -portion'with radial pins 25,4Figs. 5 and 6, whichare formedon 'the 90 outer ends. o-f the gear teeth 22 and 'are adapted t'ente'rVfeed orifices- 27 formed in the central portion of the sheet 23. The

perforations' 27 have' a function distinct `from from that of.th'e'key-operating oriv85 fces, namely,'to engage the pins 25 so that'there is always a positive feeding engagement between the feedrollandthe sheet 23.

The key operating perforations 24 are formed in accordance with thematter which 10Q i's to be printed by the typewriter, eachIperfox'vation 24" representing a printing character and key lever. Asindicated bv Fig. 7 5 the key-operating perforationslalterlfatelengthwise of the sheet 'with the feed perforations 27 so that'a per-:

5 Wheel, the teeth of the latter tviil bear inoperatively en the Sheet,as lindiceted ject through said perforation and enter the' space betweentwo adjacent teeth oi' the feed roll, se that the ster Wheel isinterengaged with the feed, roll and positively rotated thereby,asindicated by Fig. 4. This'move- ,ment of the star Wheel ie utilized todepress the corresponding typewriter-key 13 through the instrumentalityof e. lever 28 fuleruined at :29 in the casing' section 11iand havingone of its arms extending into the path of the teeth ef the star Wheel,tin-trete-v ing; ene lever 2S for ea'ch' star Wheel. The other arm ofthe lever 28 is provided with e coupling nieinher adapted to deteehablyengage the correepending typewriter lrey 13. As here shawn, saidcoupling member includes en in7 er portion 3G pivoted at 3l to thelek-er 28. and provided with a, screwthreaded extension and en outerJortion 33 haring e tapped eriice to receive the portion 3i? and e.key-hole siniped slot 34 adapt- 35 ed .to detaehebiy engage a headedstud 85 on a lrey 13. When e. star Wheel is :it rest the lever Q8 bearson thevupper side of one of its teeth, es indicated by Figs; l and 3,the key i3 being at the Same time in its" norm-.il 40 position.

feed roll through a key-operating perfor@- tion 24e in the muster-sheet,the arm of the lever hearing onthe star Wheel is raised, as indicated byFig. 4C, and the opposite end is depressed, the depressed yend actingthrough the described connection to depress the key 13 and cause theprinting ot the corresponding` character. The rotation of." the star '5Gwheel is Continued until the engaged tooth recedes 'troin the. feedroll, the'star Wheel vagain assuming the inoperative position shown byFig. 3, until the next perforation y 24 reaches 'ene of its teeth.I Thefeed roll may be rotated by any suitableineens euch as m electric motor36` located in the casing section 16 :ind'a-train Vof gears connectingthe shaft of the motorl with the feedroli. As best shown in Fig. 2,vthehuhs i9, to which the ster Wheels 2O 'are secured, are fittedclose-together. and te the shaft 18 so that Whensaid shaft i8 visrotated there Wilt be a constant tendency te rotate the4 said hubs- 19in order that, Whenever e perforalVhen the star Wheel is engaged by theVend et a teot k'. teoti to @destinen n the lne-ritira v-to retnte 'thest Aing te e slieift t0 are perni-itt operating;
